AC Repair & Air Conditioning Repair in the Salt Lake Valley
Fast, honest AC repair on every brand — central air conditioning, heat pumps, and ductless systems. Whether your air conditioner won’t turn on, is blowing warm air, freezing up, or just can’t keep up, our air conditioning repair techs find the real cause, show it to you, and quote it before any work starts. Every air conditioner repair is tested before we leave.
Air conditioning repair, diagnosed by the numbers
Most warm-air calls trace to one of a handful of measurable failures. We find which one with instruments, not guesswork.
Canyon Comfort handles AC repair and air conditioning repair on every make and model across the Salt Lake Valley. Every diagnostic runs the same sequence: we read the temperature split across the evaporator coil, check static pressure and airflow, measure superheat and subcooling on the refrigerant circuit, test each capacitor’s microfarad rating against the nameplate, and check amp draw on the compressor and the condenser fan motor. Those readings point to the actual failed component — instead of swapping parts and hoping.
Your $80 diagnostic is credited toward the repair, and every fix is verified under load — temperature split and amp draw back in spec — before we leave. When a system is genuinely past its service life, we’ll show you the numbers behind a repair-or-replace decision and your AC installation & replacement options.
Common AC repairs we do — and how we do them right
Most air conditioning repairs come down to a handful of failures. Here’s what they look like and the correct way to fix each one.
AC won’t turn on — failed capacitor or contactor
A blown run capacitor is one of the most common reasons an air conditioner hums but won’t start, or the outdoor fan won’t spin. The contactor (the relay that sends power to the compressor and fan) also pits and burns out over time. The right air conditioning repair isn’t just swapping the part — we test the capacitor’s microfarad rating against spec, check the contactor and incoming voltage, and confirm the compressor and fan motor actually draw correct amps once power is restored, so the same failure doesn’t come right back.
AC blowing warm air — low refrigerant or a stalled condenser fan
Warm air with the system running has two common causes. The first is low refrigerant, which almost always means a leak. The right long-term fix is to find and repair it — we locate the leak (electronic detector, bubble test, or dye), repair or replace the leaking component, pull a deep vacuum, then weigh in the exact charge and confirm superheat/subcooling are in spec. That said, if you’re planning to replace the system in the next year or two, a simple refrigerant top-off (where EPA rules allow) can be the sensible, lower-cost way to get you through — we’ll lay out both options and let you choose.
The second cause is a failed capacitor on the outdoor condenser fan motor. Many units run a single dual-run capacitor with two sides (HERM for the compressor, FAN for the condenser fan). When the fan side weakens or fails, the condenser fan stalls, the system can’t reject heat, head pressure climbs, and the air inside goes warm — often with the compressor tripping on high-pressure or thermal overload soon after. We read the capacitor’s microfarads on both terminals against the nameplate, confirm the fan and compressor draw correct amps, and replace with a correctly-rated capacitor so the fan moves air across the coil again.
Frozen evaporator coil & iced-up AC
Ice on the indoor coil or the refrigerant line means airflow or refrigerant is off. We don’t just thaw it and leave — we trace the root cause: a dirty filter or coil choking airflow, a failing blower, or low refrigerant from a leak. We clean what’s restricting airflow, correct the charge if needed, and verify the coil stays cold without freezing, so your AC actually cools again.
Hard-starting compressor — we install a soft start
When a compressor strains to start, draws high amps, or trips the breaker on startup, we measure winding resistance and locked-rotor versus running amps and check the start components before condemning anything. When a compressor needs starting help, we install a soft start rather than a standard hard-start kit. A soft start ramps the compressor up gradually instead of jolting it on at full force, which means far less electrical and mechanical stress, quieter starts, no light flicker or nuisance breaker trips, and a longer compressor life — it’s simply better for the equipment. If the compressor itself is failing, we’ll show you the readings and the honest repair-or-replace math.
Weak airflow & failing blower motor
If the air conditioning runs but barely any air comes out of the vents, the culprit is often the indoor blower motor, a failed capacitor on the blower, or a clogged coil — not your ductwork. We test the motor and its capacitor, clean the blower wheel and indoor coil where airflow is actually lost, and get full, strong airflow back so every room cools.
Clogged condensate drain & water leaks
A puddle by the furnace or a safety switch shutting the system off usually means the condensate drain is clogged. We clear the drain line, flush it, and check the pan and float switch — the float switch is what shuts the system down before the pan backs up and overflows into your furnace. We make sure the AC drains properly so it isn’t tripping off.
Thermostat & control problems
Sometimes the “broken AC” is a dead thermostat, a wiring fault, or a tripped float/safety. We confirm the controls and wiring before we ever recommend a part — because the cheapest air conditioning repair is the one you didn’t actually need.
We don’t call it fixed until the numbers say so
A lot of what looks like a five-minute air conditioning repair isn’t. Done right, a refrigerant repair means recovering the old charge, pulling a deep vacuum to remove every trace of moisture, brazing clean joints, weighing in the exact charge, and testing the result. Electrical repairs get verified under load. We also use an inspection camera to look inside the system — the coil, blower, and ductwork — for restrictions, blockages, and dust or debris buildup that quietly rob efficiency and air quality, so you can see what we see.
Before we consider any job complete, we measure static pressure — a reading that’s rarely checked on a service call, yet it’s the #1 hidden cause of comfort problems, high bills, and early equipment failure — along with airflow, temperature split, and amp draw, to confirm the system is actually running to spec. Then we email you a System Health Report with the readings — so you’re not taking our word for it, you have the numbers. That documented, to-spec result is what we call a Canyon Comfort Verified Repair.

Air conditioning repair questions
My AC is running but blowing warm air — what’s wrong?
Usually low refrigerant from a leak, a failed capacitor or compressor, or a frozen coil. We diagnose the real cause and fix it — and if it’s refrigerant, we repair the leak and weigh in the correct charge. See common AC problems & what you can do →
